Marches and other displays of solidarity are popping up across France and Europe in the wake of the deadly attack on the offices of satirical weekly magazine Charlie Hebdo.

Many of them are being captured on social media under the hashtag #JeSuisCharlie. On the afternoon of Jan. 7, the words appeared on Twitter over 21,000 times in just an hour.

In the French capital, Parisians held up pens in a show of support for freedom of expression.
